Avalanche Summary
No new avalanches have been observed since last Wednesday when small loose wet avalanches were noted up to size 1 in steep terrain, entraining the top 15 to 20 cm of snow. However, some rather large blocks of snow were observed to topple over from the base of a steep, rocky outcrop depositing a 10 m wide debris pile across a snowshoe trail on Monday.
Snowpack Summary
A spring-like, melt-freeze crust has formed on most aspects but will likely soften by the afternoon with continued warm temperatures and high freezing levels forecasted for Thursday. In shaded areas on north aspects at upper elevations feathery, surface hoar and sugary, faceted snow may still exist. Below the snow surface, the upper snowpack is well-settled an sits on the late-November rain crust. This crust is now buried approximately 120 cm at 1300m elevation, and is up to 30 cm thick. Beneath the crust, the lower snowpack is wet to ground. Below treeline the snow pack is thin and there are many early season hazards. Snowpack depths range from 30 cm at 800 m elevation to 180 cm at 1220 m.
